DISTILLING AND CONDENSING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 250,965, dated December 13, 1881.

Application filed September 12, 1881. (No model.)

To all whom it may concern:

Beit known that I,MIcHAEL D. PETERMAN, of Penn township, (White Ash P. 0.,) county of Allegheny, State of Pennsylvania, have invented or discovered a new and useful Improvement in Distilling and Condensing Apparatus and I do hereby declare the following to be a full, clear, concise, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which-like letters indicating like parts- Figure 1 is a sectional elevation of my improved apparatus. Fig.2 is a detached view,

1 5 in perspective, of a portion of the condensingcoil which I employ. Fig. 3, by a detached sectional view through two sections of coil and the condensing-cylinder, illustrates a modified form of construction and Fig. 4. is a detached 2o sectional view, to an enlarged scale, of an injector adapted for use in my improved apparatus,- as hereinafter described.

My invention relates to certain improvements in apparatus for distilling and condensing alcoholic and other spirits, fermented mashes, and other like material, and fluids generally, wherein I employ an upright still suspended in a water chamber or jacket over the fire, in combination with the condenser, and a waterpipe for carrying the water of condensation from the converter to the water-jacket surrounding the still, and wherein I also employ a coil or worm triangular in cross-section.

On any suitable foundation, R,I'constructa 3 5 water-chamber, A, of suitable size for containing a body of water which shall fill the space beneath and partially or entirely around the height of the still B, and in such foundation I make fire-space A, of suitable size and ca- 0 pacity for heating the water in the chamber A, and thereby heat the contents of the still B. The still 13 is suspended within the top of the chamber A, so as to form a close joint at the top, and is of capacity such as is desirable 5 for the work to be done. A goose-neck, D,

leads from the dome of the still to the condensing apparatus P, but passes through the exterior wall thereof by a slip or other suitable joint, E, so as to enter the coil F. The condenser P is divided vertically by a casing, K, which extends from the bottom of the con denser P to a point near its upper end, at which point it is connected with the outer casing by the flanged section G, which, for convenience, may slip inside the inner section, K, as illustrated in the drawings. The flange G is provided with a series of holes, g, through which to establish connection between the inner andouter chambers of the condenser. Cold water for condensing purposes is supplied to the outer chamber of the condenser by any suitable pipe, H, and the water thus supplied, after filling the outer chamber, passes, by the holes g, into and fills theinner chamber. The

water thus supplied will, as the work of condensin g goes on, become somewhat heated, especially the upper part of it, and I make use of the condensed partially-heated water to fill the water space or jacket of the chamber A. This may be done by overflow through any suitable pipe, 0 but in order to insure a sufficient supply of water in the chamber A, I prefer to use the ordinary steam-injector. For this purpose a pipe, 0, may be led from the steam-space in the chamber A, above the or- 7 5 dinary water-line, to a point in said chamber below such water-line, and the pipe 0 be connected therewith at the head 0, so that the steam-injector, being arranged in the head and in or across that end of the pipe 0 shall oper- 8o ate on well-known principles to force water from the condenserto the chamberA. In Fig.

4 I have illustrated by sectional view one form of injector adapted for this purpose, having outer head, 0, combining-tube o steam-nozzle 0 and check valve 0 If desired, the check-valve may be omitted also,other wellknown and suitable injecting or siphon-pump devices may be employed, as desired,in place of the one illustrated. Cocks c and c are to 0 beadded for the usual purposes.

The worm F, which constitutes an important feature of my invention, is made triangularin cross-section at all, or substantially all, portions of its length, and is coiled on or around 5 the cylinder K, with one of its flat sides against said cylinder, and the other sides projecting into the outer chamber, m. By this construction I get what I believe to be the best relative proportions of interior area of the coils F and exterior cooling or condensing surface. The interior size of the coil is to be such as may be required for the work to be done, and this being fixed, the triangular form of coil will give, as Ibelieve, the largest amount of exposed surface practicable in such an apparatus, by which to effect the desired condensation; but instead of making the coil triangular in cross-section and winding it on the cylinder K, it may be made of V shape, as illustrated in Fig. 3, with narrow flanges 8 along the edge of the V, and such V-shaped trough may then be wound around the cylinder K, with its open side toward the cylinder, and secured thereto by rivets through the flanges s and through thecylinderK,asillustrated in Fig. 3, so as to present on all sides of the coil only a single thickness of metal.

At a, I have shown an escape-pipe and cook for drawing off the condensed product. Other cocks may be added at pleasure-as, for example, a pipe and cook, B, for emptying the still when necessary, and also try-cocks a, for ascertaining the height of the water in the chamber A; also, bymeans of the pipes 13 and cock 13 I make provision for carrying off-any steam which may be generated in the chamber A, and which may be useful for mechanical purposes. The pipe B may lead to any suitable steam-engine, heater, or other apparatus where the use of steam is desired.

Atf, I have shown a man-hole or supply-orifice, through which the still may be charged or cleaned, and a drain-pipe may be attached to the water-chamber, as illustrated by dotted lines atf.

I claim herein as my invention- 1.. An upright still suspended in an upright water-chamberover a fire,in combination with a condenser and water-pipefrom the condenser to the water-chamber, substantially as setforth.

2. The combination of upright still and Water-chamber, a condenser, a water-pipe from the condenser to the water-chamber, and an injector, substantially as set forth.

3. In combination withthecondensing-chamber of a still, a coiled worm-pipe polygonalin cross-section, having one of its sides in contact with the wall of the condensing-chamber, substantially as set forth.

In trstimony whereof I have hereunto set my hand.
